Abstract
Ralstonia solanocearum is a pathogenic bacteria that attacks tomatoes and causes wilt disease. Many efforts have been made to control this disease through cultivation, use of chemical pesticides, and development of resistant varieties, but bacterial wilt disease remains a serious problem economically. Nowadays, many biological controls are being developed using microbes. The use of Bacillus spp as an unfriendly microbe is very potential to control because it has pathogenic inhibitory activity. This study aims to obtain bacterial isolates of Bacillus spp which can suppress the development of bacterial wilt disease in tomato plants. The research was conducted in vitro at the Laboratory of Plant Physiology in the Agriculture Faculty, Unpatti. The results showed that Bacillus niabensis strain PT-32-1 and Bacillus subtilis strain SW116b could inhibit Ralstonia solanacearum, wilt disease in tomato plants in vitro.
